PORTLAND, Ore. - A dog that suffered smoke inhalation in a North Portland fire is still recovering at a pet hospital.

'Wolfy' was rescued Saturday evening when a fire broke out at a home in the 7800 block of N. Hodge Avenue. A special dog oxygen mask was used at the scene to help Wolfy breathe.

Firefighters had a strange encounter with the homeowner that day. Police say when crews arrived on the scene, there was a 69-year-old man on the front porch who was swinging a sword and yelling incoherently.

Police had to use a stun gun to subdue him so firefighters could do their job. Once they were able to get inside, crews found the dog and got the blaze under control in about 20 minutes. The damage is estimated at $40,000 and the cause remains under investigation.

The man with the sword, who has not been identified, suffered a cut from broken glass and was taken to a hospital for a mental evaluation. Police said this incident was the second time in a month that the man had gone through a mental crisis and officers had to respond.
